No.
In any triangle on a plane surface, each exterior angle is equal to the sum of the other two interior angles.
Suppose A,B and C are the interior angles and a b and c the corresponding exterior angles.
Then a < 90 implies that B + C < 90
and b< 90 implies that A + C < 90
This gives B+C+A+C < 180 so that A+B+C < 180 which contradicts a property of triangles.
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
There are many possible shapes with two acute angles.
In an acute triangle, all three angles are acute.
there are three acute angles in an acute triangle, because there are three corners.
Yes, that's possible. For instance a triangle with the angles 70°, 70° and 40° is both acute and isosceles.
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.
It is possible for an isosceles triangle to be an acute triangle because, in an acute triangle all the angles have to be less than 90o.
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
Yes
yes it is
In any right triangle, the two angles at either end of the hypotenuse are both always acute angles. But I don't think that would be called an 'acute' triangle, because an acute triangle is one in which all three angles are acute ones.
Every triangle must have either 2 or else 3 acute angles. The least possible is 2.
yes.. isosceles
A right triangle is a triangle with one of its angles being 90o. The requirements for the other two angles are that they both be acute and total to 90o. Therefore, the largest possible acute angle in a right triangle is 89.99999...o.
There are many possible shapes with two acute angles.
In an acute triangle, all three angles are acute.
